我使用“maven-bundle-plugin”编写了一个OSGi包（其中我尝试将“jruby-complete-1.4.0.jar”作为osgi包，注意只有依赖是“jruby-complete-1.4”。 0.jar“）..当我使用diag命令（#diag XX）通过osgi控制台检查捆绑包时，它说有些包丢失了;
osgi> diag 51
reference:file:dropins/jruby-complete-1.4.0.wso2v1.jar [51]

我的pom就像;

所以，我尝试在<Import-Package>选项中添加那些“可选的缺失包”，如pom [2]
但它提供了更多的问题，如;

我如何克服上述问题？ 我正在出口一些包，我需要其他包...我在这里做错了什么？
答案 0 :(得分：6)
这些包是可选导入，因此这里不一定有任何问题。
海报修改后的问题更新：
bundle插件通过检查bundle中的字节码发现了这些依赖关系。它们通常是必需的依赖项，但由于某种原因，您通过添加<Import-Package>*;resolution:=optional</Import-Package>使它们成为可选项。不知道为什么你这样做但从不介意...
解决包的正确方法是找到导出它们的包。例如，您的捆绑包需要包org.jgrapht。因此，您需要安装导出该包的包。
一个例外是sun.misc包，它显然来自JRE，但一般不应该使用。 OSGi框架默认情况下不提供此软件包，但您可以通过添加以下设置来配置它们：
org.osgi.framework.system.packages.extra=sun.misc
放置此设置的确切文件或位置取决于您的OSGi框架 - 您尚未指定您使用的是哪一个，所以不管它是什么，请查看其文档，了解如何传递配置设置。
